IMPROVEMENT IN GAS-BURNERS.

Specification forming part of Letters Patent N0. 163,929, dated June 1,1875; application filed March 19, 1875.

To all whom it may concern Be it known that I, WILLIAM J. HER- mor'r, ofBoston, Suffolk county, and Commonwealth of Massachusetts, have inventedImprovements in Gas-Burners, of which the following is a specification:

This invention relates to gas-burners, and has for its object to preventthe gas-issuing orifice of the burner from becoming stopped by the ironscale and other particles which pass with the gas through the pipes, andusually into the burner, and also to obtain the greatest amount of lightwith the least amount of gas; and my invention consists of a gas-burner,constructed as hereinafter fully described and explained.

Figure 1 is a perspective view of one of my gas-burners; Fig. 2, alongitudinal section; Fig. 3, top view, with the upper portion of theburner removed. Fig. 4 represents the interior of this removed portion,showing the end of thedistributing-burner; and Fig. 5 represents thedisk.

The outer shell or case of the burner consists of two cylindrical andcup-like parts, a a, screwed together, and provided at each end withinternal screw-threads to permit the burner-shell to be connected with afixture, and to receive the tips for governing the exit of the gas. Inthe lower portion of the burner-shell is placed a plate, Z), providedabout its periphery with radial slots, and the plain center of the plateis larger than, and is located immediately above, the opening in thefixture, through which the gas passes into the burner, and particles ofiron scale, rust, and other impurities moving with the gas strikeagainst the plate, and are broken or checked, the gas passing throughthe openings in the plate and into and among the small pebbles or stonesd, where impurities which pass through the slots in plate I) arecollected.

The irregular openings" between the pebbles permit the gas to flowwithout too much obstruction. They do not corrode, and when dirty orgumrned in any way may be removed and washed.

Above the pebbles is placed a wire-gauze cover, e, to prevent thepebbles from getting into the orifice of the gas-regulatory, which ismade as a fish-tail burner, and removable from its holding-plate g,screwed into the part a. This fish-tail-burner-like piece f determinesthe quantity of gas consumed, and gas issuing from it passes into anenlarged chamber, h, from which it passes through slits a, crossing eachother, and into a cylindrical space, j, and out at the slit k of thebat-wing tip I, where it is ignited. This tip may be of any desiredstyle or variety.

The plate I) finds, or has made for it, a seat in the part a, and theholding-plate g for the piece f is screwed into the part a, and thepebbles are therefore securely held in position, and the upper part ofthe burner a 1 may be removed for the insertion or removal of a tip, f,for regulating the quantity of gas to be consumed.

The gas issuing from the piece f is delivered into a chamber, where itis allowed to expand, and the crossing slots distribute the gas evenlyin the space j, where, through the action of the tip I, which is heated,the gas is further expanded, and in such condition the gas ignited andpassing through slit 7c is found to burn with but little blue flame.

The slits and k are so proportioned with relation to each other that thepressure shall be just sufficient to permit the gas to flow withoutsinging.

I am aware that a chambered burner with an interior and an upper tip isnot new, and I am aware that shot has been placed within a chamber of aburner, and therefore I do not claim these things, broadly; but

I do claim- 1. The combination, with the chambered burner to a and itstip I, of the slotted plate b, fitted to a seat in the bottom of theburner, the pebbles, the plate g, securely fitted to the shell to, andthe removable tip or gas-regulatin g piece f, all constructed andcombined as described, to arrest the impure or other particles movingwith the gas, and to de-- liver the gas in measured quantities into thechamber, from which it is consumed through an opening in the tip I, asset forth.

2. The combination of the burner a a, regulating-tip and plate fg, tipI, and tube, provided with crossing slots 6, and fitted to the interiorof the removable shell a, and project ing within the chamber, all asshown and described.

WILLIAM J. HERRIOTT.
